Applications such as battlefield and\u0000traffic surveillance, agriculture and environment monitoring, smart homes and smart cities require a\u0000specific protocol to fulfill a specific purpose. WSN is composed of numerous tiny Sensor Nodes\u0000(SNs) along with one or more sinks, where sinks have unlimited sources of energy and SNs are battery-\u0000operated. SN tasks are to sense the data and transmit it to sink through the formation of dynamic\u0000topology. The SNs nearer to the sink rapidly exhaust their energy due to the heavy burden. Due to\u0000this, SNs became dead affecting the performance of the network lifespan. To overcome this problem,\u0000the concept of MWSN has been proposed. In MWSN, the sink can move from one location to another,\u0000and collect data from SNs. With the help of MWSN, the problem of energy holes can be resolved.\u0000An energy hole is a problem in which nodes are alive but they are not able to send the data due to\u0000low energy left. To overcome this problem, MWSN plays an important role.

The EDs are designed in a way that they can choose optimal configuration resource parameters from a set of LoRa physical layer parameters. The SF parameter has to be chosen correctly, as an incorrect one may cause collisions and interference if multiple nodes have the same SF. This paper focuses on throughput and latency optimization using an effective ADR mechanism for LoRaWAN-based IoT networks. The objective of this study is to maximize the total throughput. SF should be used by multiple nodes as it will have less Time on Air (ToA), but it may cause collision, contention, and co-spreading factor interference problems. The idea is to find an optimal SF allocation to end devices and the optimal number of total devices using the same SF to avoid collision and interference. This paper proposes a multi-objective stochastic gradient descent method to solve the constrained optimization problem for optimizing throughput and latency. This work compares throughput and latency results for the static, quasi-static, and dynamic environments. Trade-offs between latency and throughput for the simulated scenarios are also presented. The simulation results show that the throughput obtained using this technique is higher than the naive ADR approach and the existing gradient descent methods.","PeriodicalId":37686,"journal":{"name":"International Journal of Sensors, Wireless Communications and Control","volume":"128 1-2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139262679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The future of 6G technology is bright and vibrant; however, there are yet several obstacles in the way of implementing 6G networks like capacity of system, reliability, security, latency, data rate, high energy efficiency, ever-present intelligent connectivity, and recent theories. In this paper, various 6Genabled technologies are discussed like artificial intelligence, terahertz communications, wireless optical, free-space optical, backhaul network, and block chain along with associated challenges. We showcase the foundation of 6G in detail, the performance of the 6G network, and key enabling technologies that can upgrade the future of the smart world.

Patients can be monitored in real-time by a group of healthy individuals, and abnormal behaviors can be used to identify them later. Patients who do not engage in customary physical activities are more likely to suffer from stress, cardiovascular disease, diabetes, and musculoskeletal disorders. Thus, it is critical to collect, evaluate, and analyze data to determine their activities. Objectives and Methodology: Deep learning-based convolutional neural networks (CNNs) can be used to solve the problem of patient activities in the healthcare system by identifying the most efficient healthcare providers. Healthcare relies heavily on the integration of medical devices into cyberphysical systems (CPS). Hospitals are progressively employing these technologies to maintain a high standard of patient care. The CNN-CPS technique can be used by a healthcare organization to examine a patient's medical history, symptoms, and tests to provide personalized care. A network of medical devices must be integrated into healthcare. Hospitals are increasingly using these technologies to ensure that patients get the best possible care at all times. Healthcare automation can dramatically improve quality and consistency by reducing human errors and fatigue. The multiobjective optimization is achieved considering various factors like the time required to find emergency case identification, new disease prediction, and accuracy of data protection. Results: Consequently, patients are assured of receiving a consistent, attentive service at every visit. Data and orders can be stored and entered more easily via automation, market research suggests. The outcome of this article is obtained based on a comparison of various approaches in health monitoring systems, such as collection of patient data is 82.3%, new disease prediction is 80.14%, emergency case identification is 78.25%, data protection is 81.35%, immune to impersonation attack reduction is 78.36% and overall accuracy of data protection and transmission performance is 86.24% is achieved.

The captured underwater images often experience scattering and high levels of noise due to the properties of light transit within the water and the biotic movement that occurs inside the ocean bottom. Underwater cameras or devices were fitted inside the unmanned underwater vehicles (UUVs), autonomous underwater vehicles (AUVs), remotely operated vehicles (ROVs), ocean detector networks, etc to see the ocean bottom. Despite being a crucial detector for keeping an eye on underwater landscapes, modern underwater camera sensors or detectors contain a number of problems. Numerous solutions to the issues with conventional underwater photography have been put out during the last five years. With the help of the number of contributions and difficulties reported by more than 40 researchers in their research article, this study focused to mention the current underwater image processing methods. This article represents an overview of numerous underwater image-processing techniques utilized, including underwater picture de-scattering, underwater image colour refurbishment, and underwater image aspect evaluations.

In spite of many advantages, there are some limitations to such networks. Improving the system efficiency by power, energy, or relay selection optimization is quite desirable as multiple helper nodes are used in the network. Considering this crucial requirement of optimization, the proposed work presents optimal power allocation of the system. Methods: Here, tunicate-swarm optimization is implemented to improve the system parameters, symbol error rate (SER), outage probability, and bit error rate (BER). Two relaying protocols are used for analysis, i.e., Amplify-and-Forward (AF) and Differential AF (Diff-AF), with two combining schemes: Selection-Combining (SC) and Maximal-Ratio-Combining (MRC).

Firstly, research questions were formulated, followed by the search strategy definition. Based on assessment criteria, 193 papers are shortlisted and thoroughly analyzed to extract research-related information. Results: The techniques identified in 193 articles are comprehensively mapped from four aspects: data acquisition, data preprocessing and feature engineering, learning algorithm, and evaluation. Each technique is examined for its strengths and limitations to assist application developers in selecting the best one for their needs. The prevailing challenges and upcoming research opportunities are thoroughly explored. Conclusion: The ever-expanding literature in the field necessitated an update to the status of HAR literature. Compared to other reviews that focused on specific methods, fields of application, and datatypes, to the best of our understanding, this is the first evaluation of its kind that provides a broader mapping of HAR approaches.

As a result of these advantages, textile antennas are gaining popularity these days.\u0000\u0000\u0000\u0000There are different applications of textile antennas, but the main application or aim is to wear them comfortably and observe different body signals for analysis of different health parameters, like temperature, heart rate, blood pressure, etc., as the compactness of the antenna bending losses is less.\u0000\u0000\u0000\u0000In the design of an antenna, jeans fabric is employed as the substrate because this material is sturdy, stiff, of little density, accessible, and inexpensive with electromagnetic properties ℇr = 1.6 and tan ẟ = 0.01, and copper is used for the conducting patch and ground.\u0000\u0000\u0000\u0000This antenna operates in the industrial, scientific, and medical radio (ISM) band at 2.4 GHz with patch dimensions of 25 x 20 mm, making it proper for body-worn purposes. Because the antenna is so small, it can be readily mounted on an arm for health parameter monitoring with minimal bending. In sweaty conditions, it also operates in the ISM band.\u0000\u0000\u0000\u0000The simulation, fabrication, and body wear results are all included in the results section. As a result, these novel fibre antennas are useful to incorporate into shirts and coats for easy health monitoring with minimum loss.\u0000","PeriodicalId":37686,"journal":{"name":"International Journal of Sensors, Wireless Communications and Control","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87577471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
